Housed in a 20-SOIC wide-body package (7.50mm width), the SN74AHC244QDWRG4Q1 uses the standard 1.27mm pitch SOIC footprint common on automotive PCBs. The wide body gives better creepage distance for high-vibration or conformal-coated assemblies compared to the narrow SOIC variant. It is a surface-mount part, so no through-hole rework — plan for reflow soldering with the usual 260°C peak profile.

Frequently asked questions
Is SN74AHC244QDWRG4Q1 RoHS compliant?
Yes, it is ROHS3 compliant, meeting the current European Union restriction levels for lead and other hazardous substances.
How does SN74AHC244QDWRG4Q1 compare to a standard 74HC244?
The AHC family also offers slightly lower propagation delay at equivalent supply voltages. For non-automotive designs, a commercial 74AHC244 may be a lower-cost alternative.
